description

Bakalaura darbs ir uzrakstīts latviešu valodā, datorsalikumā uz 32 lapām. Tas satur 14 attēlus, 3 tabulas, 15 atsauces uz literatūras avotiem. Darba mērķis: novērtēt, cik lielā mērā skolēniem tiek noslogota acs akomodācijas sistēma dienas laikā. Rezultāti: Bērnu akomodācijas sistēma dienas laikā ir pakļauta nogurumam, jo skolas dienas laikā akomodācijas amplitūda būtiski samazinās (p<0.05). Vecuma grupās 8,5 un 12,8 akomodācijas amplitūda (AA) samazinājās par 0,80 D un 14,8 gadu vecuma grupā AA samazinājās par 0,87 D (p<0.05). Gan pirms, gan pēc mācību stundām skolēniem vidējās AA vērtības bija zemākas nekā aprēķinātā minimālā akomodācijas amplitūdas vērība pēc Duanes-Hofstetera formulas (p<0.05). AA starpība ar minimālo normā pieņemto vērtību 2. klasē bija 0,91 D, 7. klasē– 0,74 D un 9. klasē – 0,57 D.
